Fluorescent reflective tape is a type of retroreflective sheeting designed to enhance visibility in both standard and low-light conditions by combining fluorescent colors with reflective properties. This type of reflective tape typically features a fluorescent base layer created using special inks that emit a specific kind of light. The fluorescent effect is akin to glow-in-the-dark tape, with the distinction that, in fluorescent materials, all the absorbed light is released simultaneously, and no light is stored. This phenomenon makes the color layer highly visible during the day, especially under natural or UV light.
It’s important to note that standard colors of reflective tape are visible and vivid in the daytime, but they do not match the visibility of fluorescent colors. Fluorescent colors, due to their unique characteristics, are particularly conspicuous. Additionally, fluorescent reflective tape incorporates reflective elements, usually micro prisms, that become illuminated when exposed to artificial light sources at night, such as vehicle headlights. These reflective elements reflect light back to the source.
As seen in the picture below, the two rolls on the left are fluorescent, while the two on the right are not. For most viewers, the fluorescent colors are more visible.
The combination of fluorescent and reflective qualities makes this type of tape highly effective for applications where visibility is crucial, such as in work zones, construction areas, school zones, and on emergency vehicles. The primary function of fluorescent colors, often in shades of orange, yellow, or green, is to enhance daytime visibility, while nighttime visibility is facilitated by the retroreflective characteristics of the film. In other words, fluorescence is mostly a daytime visibility enhancement characteristic.
Fluorescent reflective tape is commonly used on vehicles, bicycles, helmets, safety gear, signage, and other surfaces to improve visibility and reduce the risk of accidents in various settings. The specific materials and manufacturing processes can vary, but the overall goal is to create tape that stands out both in daylight and when illuminated by artificial light sources.
